The LNK6779K-TL is the newest device in the power management integrated circuit (PMIC) family and is specifically designed for AC/DC converters and offline switchers. It is an ideal solution for a variety of cost and size sensitive applications, especially those where thermal management is a challenge.

The LNK6779K-TL offers an all-in-one solution for AC/DC and offline switcher applications, including such features as low Standby Power (<250μA typical at 115VAC or 12VAC and 20mA typical at 230VAC or 24VAC) and on-chip power MOSFETS. It can provide up to 50W output power and is designed to meet the latest EN 55103-2 emissions standards.

The LNK6779K-TL offers a wide range of operational benefits, intended to help reduce the overall system cost, power consumption, size, and design time. It is equipped with a high-speed PWM comparator and provides protection against over-voltage, short-circuit, and over-load. It uses switch-mode technology to provide up to 90% efficiency. Its operating temperature range is from -20°C to +50°C (100°C for industrial).

The primary purpose of the PMIC – AC/DC converters and offline switchers – is to convert the incoming AC power to a DC voltage level suitable for use in electronic systems. Typically, this means converting the incoming AC voltage to a DC voltage of 12V or 24V. The LNK6779K-TL offers a wide input range, from 85VAC to 265VAC, making it an ideal solution for applications such as solar power, battery backup systems, and automotive applications, among others.

The LNK6779K-TL works on the principle of voltage switching and pulse-width modulation (PWM). PWM is used to control the output voltage and power finely, enabling the device to provide excellent efficiency and stability. The device also includes an auto start feature, enabling it to start automatically upon receipt of an input voltage, providing a reliable and cost-effective solution for many industrial, automotive, and consumer applications.

In summary, the LNK6779K-TL is a versatile PMIC device that is specifically designed for use in AC/DC converters and offline switchers. It offers a broad range of features and benefits, including low standby power, high efficiency, excellent stability, and a wide operating temperature range. It is ideally suited for a variety of cost and size sensitive applications, especially those where thermal management is a challenge.
